The invention relates to an EVA (ethylene-vinyl acetate copolymer) adhesive heating extruder, belonging to the technical field of polymer material preparation. The EVA adhesive heating extruder comprises a cylinder and a screw arranged in the cylinder and driven by a motor, wherein electric heating plates are uniformly stuck to the outer wall of the cylinder; temperature sensors are uniformly arranged in the space keeping away from the screw in the cylinder at intervals; the output ends of the temperature sensors are connected with an analog/digital conversion module in series and then are connected with the data input end of a central processing unit (CPU); flowmeters are arranged at an opening at the bottom of the cylinder; the output ends of the flowmeters are connected with the signal input end of the CPU; the electric heating plates are controlled by the CPU. The EVA adhesive heating extruder provided by the invention has the beneficial effects that the electric heating plates are arranged on the outer wall of the cylinder and are used for heating and maintaining the temperatures of EVA adhesives in the cylinder; the temperature sensors are also arranged in the cylinder and are used for acquiring temperature signals; the CPU is used for automatically controlling the powers of the heating plates according to the temperatures to prevent overheating.
